1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundPostpartum hypertension can be persistent, following a pregnancy complicated by hypertension, or new onset (de novo), following a normotensive pregnancy. The aim of this study is to estimate the incidence and identify risk factors for de novo postpartum hypertension (dn-PPHTN) among a diverse safety-net hospital population.

methodsWe conducted a retrospective cohort study of 3925 deliveries from 2016 to 2018. All blood pressure (BP) measures during pregnancy through 12 months postpartum were extracted from medical records. Patients with chronic hypertension or hypertensive disorders of pregnancy were excluded. dn-PPHTN was defined as 2 separate BP readings with systolic BP ≥140 mm Hg and diastolic BP ≥90 mm Hg at least 48 hours after delivery. Severe dn-PPHTN was defined as systolic BP ≥160 and diastolic BP ≥110. We examined risk factors individually and in combination and timing of diagnosis.

resultsAmong the 2465 patients without a history of hypertension, 12.1% (n=298) developed dn-PPHTN; 17.1% of whom had severe dn-PPHTN (n=51). Compared to those without dn-PPHTN; cases were more likely to be ≥35 years, delivered via cesarean, or be current or former smokers. Patients with all of these characteristics had a 29% risk of developing dn-PPHTN, which was elevated among non-Hispanic Black patients (36%). Approximately 22% of cases were diagnosed after 6 weeks postpartum.

conclusionsMore than 1 in 10 patients with normotensive pregnancies experience dn-PPHTN in the year after delivery. Opportunities to monitor and manage patients at the highest risk of dn-PPHTN throughout the entire year postpartum could mitigate cardiovascular related maternal morbidity.
